[PD-dev] dlopen error _class_addlist

[Miller Puckette]

Hmm... I think if there are 100s of undefined symbols the extern loader
in Pd only reports one of them (seemingly choosing one at random).  So this
is probably a failure of dlopen to see any symbols from the calling pd at
all.

But why this should happen for arm and not for intel arch escapes me...
perhaps Mac has added some more hurdles to dynamically loading code, but
only turned them on for arm?
